I LOOM ATTACHMENT.

To a ZZ whom it may concern:

e it known that 1, CHARLES E. CHAM- nnus, a citizen of the UnitedStates, residing at Asheville, in the county of Buncombe and S'tateofNorth Carolina, have invented new and useful Improvements in LoomAttachments, of which the following is a specificat1on.

This inventionrelates to looms and has for its object the provision ofnovel means for attaching thecheck trap which passes around the pickerstick for the purpose of stopping the travel of the shuttle.

Another object is to provide means for securing the check strap in amanner to per mit of adjustment so as to properly position and regulatethe length of the strap.

A further object is to provide a strap attaching means, by which thelength of the strap necessary for the proper operation of is materiallyreduced, thereby resulting in a saving of material, especially where anumber of looms are in operation.

Other objects and advantages of the inappear as the scription is read inconnection with the accompanying drawing In the drawings: Figure 1 is abottom plan View of the magazine end of the loom lay illustrating thearrangement. of the check strap and its securing clamp and the manner ofattaching the same to the loom.

F ig. 2 is a side elevation of the subject matter of Fig. 1.

Fig. 3 is a longitudinal sectional view through the clamp, with the endsof the strap in position.

Fig. 4 is a detail perspective view of the clamp plate used at themagazine end of the lay. V

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts, the lay i indicated at 10 and isprovided with the usual slot 11, for the passage of the picker stick 12,a fragmentary portion of'the shuttle box being indicated at 13. Theseelements maybe of the usual or any preferred construction and form nopart of the present invention, which resides in the manner of attachingthe check strap which passes around the picker stick 12 in the usualmanner, saidstrap being indicated at 14. 0

As before stated, the invention resides 1n the mannerof securing the,strapl to the Specification of Letters Patent. i

loom, and for this following dey properly positioned Patented'Nov. 1,1921. Serial No. 308,955.

purpose there is provided at each end 'of the lay a bracket 15, whichmay be of any suitable construction and secured in position by anydesired means. Secured to eachof the brackets is a clamp 16, the clampat the magazine end of the loom being formed of a plate 17. This platehas substantial parallel side edges and is provided intermediate its endwith a longitudinally disposedslot 18, for the passage of a bolt or studand by meansof: which it is secured to thebracket 15. The plate iscurved at each end, and these ends are rounded as at 20, and areprovided with longitudinally disposed slot 21. Eachend of the strap 14engages over the rounded ends 20 of=the plate and is clamped betweensaid plate and a clamping strip 22, which is adjustably secured to theplate through the medium of a bolt 23, which passes through the slot 21and through an opening 24: in the strip 22. These strips are providedalong one edge with a head 25, so that a portion of the strips is spacedfrom the plate for the reception of the ends'ofthe strap 14:.

By means of the slot 18, the plate may be with respect to the plckerstick, while the slot 21 provides for the proper adjustment in thelength of 86 the strap.

The clamp 16 at the opposite end of the lay is in all respects similarto the clamp just described, except that the plate which is indicated at26, has its central slot 27 90 offset from the end slots 21, so that toprovide for this one longitudinaledge of the plate is offset, asindicated at 28.

By the use of the improved clamp, the materialreduction in the lengthnecessary for the strap is obtained, the strap now in use being fromtwenty-two to twenty-three inches in length, while the strap used inconnection with the herein described clamp is about sixteen inches inlength, so that in the initial installation the saving of six or seveninches of leather is effected, and when thestrap becomes worn, the lossis considerably less than in the former strap. Further, by securing thestrap to one side 10! of the lay, a side pull is exerted upon the pickerstick which results in more gradual check of the shuttle and relieves toan appreciable extent pressure of the springs and the shuttle pointerand adds to the life of the shuttle. In addition this gradual checkeliminates a sudden jar and pull upon the strap at the end of the strokeandtherefore adds to the life of the strap.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims. V

Having described the invention, what is claimed is: V

1; A picker check for looms comprising a flexible loop extending aroundthe picker stick, a plate adjustably secured to one side of the layandmeans for securing the loop to the plate, 'whereby a side pull willbe exerted upon the picker stick at the end of its stroke. V 1

2. A picker check for looms comprising a strap extending around thepicker stick, an elongated plate secured to one side of the lay andmeans located at each'end of theplate ior'securing each end of the strapto pro'vide a loop, whereby a side pull will be exerted upon thepickerstick at each end of its stroke- 5 l 3. A picker check for loomscomprising a strap extending around the picker stick, a plate secured toone side of the lay and transversely curved clamping strips adjustablysecured to each end of the plate for securing the ends of the strap toprovide a loop, whereby a side pull will be exerted upon the pickerstick at the end of its stroke.

4. A picker stick for looms comprising a strap extending around thepicker stick, a curved plate having a longitudinally disposed slotintermediate its ends for adjustable attachment to one side of the lay,curved rounded ends for said plate, said curved rounded ends also beingprovided with longitudinally disposed slots, clamping strips forsecuring the ends of the strap to each end of the plate and clampingbolts passing through the last mentioned slots and engaging the clampingplates and strap, whereby a side pull will be exerted upon thepicker'stick at-each end of its'stroke.

In testimony whereof I- afiix my signature.
